Re: [Elecraft] Tin Whiskers
Tin Whiskers has primarily been a problem inside hermetic seals where there is little or no atmosphere and in weightless environments. Satellite and space probe instrument makers are the most concerned (Hence NASAs involvement). Has anyone heard of the tin whisker as a problem in automotive or home entertainment environment?

The ELV directive (automotive) exempts lead solder. They _know_ they're forcing planned obsolescence upon the public. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] Tin Whiskers
I have never purchased extended warrantees on electronics, but I may start. Lead is being outlawed in electronics in Europe, and most of the rest of the world is going the same way. I work in automotive electronics, and have been aware this was coming for years, but our customers are now starting to demand lead-free products. There is lots of work going on to figure out how to make reliable products without lead, but I expect there will be lots of problems.
